With the container is applied, and cam over the container. The brim full oi' plastic or frozen material directly smallest diameter of the rib is less than the excontacting the disk of the closur a Substantial terna! diameter of the container so that as the' 55 cap is forced home, the rib is expanded and compressed or flattened as indicated in Fig. 3.. The

`diameter of the flat portion of the disk I3 is sutilclently great so that there is no danger of snagging the container mouth on the lower edge of the disk rim I4, substantial clearance being provided between the members Ill and I4 as indicated in Fig. 3. Furthermore. the inwardly present rib I8 with its tapering or rounded lower cam surface automatically centers the flange I3 with respect to the container as the cap is thrust home and obviates any danger of the container mouth engaging the disk rim Il.

The upper part of rib I8 contacts or. approximately contacts the flange I4 of disk I3 and thus coacts with bead I6 to lock the disk in place. Since the skirt I1 of the flange-forming member I5 is of substantially greater diameter than the container I0, no careful manual manipulation for fitting the closure to the shell is required but the cap drops over the shell and the latter is automatically centered with respect to the inclined or tapered under side of rib I 8.

The bending or forming of bead I6 and rib I8 appreciably stiffens the Bange-forming element I5 so that it has no tendency to lose its circular shape even though made of relatively light material. The ice cream which lls the container III reinforces this shell and sustains its shape and permits the shell to positively expand or compress the rib I8 as the closure is pressed home. No air space is present between the flat disk I3 (which makes complete peripheral contact with the container mouth) and the contents of the container. Thus as pull is exerted to remove the cap there is a tendency to create a vacuum between this disk and the ice cream which affords further resistance to removal of the closure.

The casual handling of the caps or closures prior to their application to the container will not result in dis-assembly o f the disks with respect to the ilange forming elements. The container is of regular cylindrical form which is distorted as an incident of the application of the cap is the annular compressible or yieldable rib of the cap itself.

and the; only member' In the drawing the thickness of the material and the extent to which the rib is flexed or expanded or flattened as the cap is applied has been greatly exaggerated in order to more clearly visually depict the action which occurs. t l

Having thus described my invention, what I claim as new and desired to secure by Letters 1. A package including a container having a peripheral wall of fibrous material, the upper portion of said wall being cylindrical, a plastic comestible material normally liquid at body temperature and-filling said container to the brim, a anged cap-closing the mouth of said container and includinga flat disk portion of greater diameter than said peripheral wall and having complete peripheral contact with the upper edge of said peripheral wall and also having contact with the entire top surface of said comestible material, land a flange portion of materially larger diameter than said peripheral wall and presenting an inwardly directed bead spaced below said disk and also spaced above the lower edge of said flange whereby upon applying said cap the lower edge of the flange will loosely fit over the upper end of said peripheral wall, and upon forcing the cap downwardly said bead will tightly and frictionally engage with the outer surface of said peripheral wall to retain said cap.

2. A container having a peripheral wall of fibrous material, the upper portion of said wall being cylindrical, and a flanged cap closing the mouth of said container and including a flat disk portion of greater diameter than said peripheral wall and having complete peripheral contact with the upper edge of said peripheral wall, and a flange portion of materially larger diameter than said peripheral wall and presenting an inwardly directed bead spaced below said disk and also spaced above the lower edge of said flange whereby upon applying said cap the lower edge of the flange will loosely t over the upper end of said peripheral wall, and upon forcing the cap downwardly said bead will tightly and frictionally engage with the outer surface of said peripheral wall to retain said cap.
